Calories Burned. Your body constantly burns calories at a slow rate regardless of your level of activity, but when you perform a challenging exercise such as the plank, you burn calories at a faster rate. A person who weighs 150 pounds will burn 221 calories in an hour of performing a plank, according to FitClick. Given that you're unlikely to perform planks for an hour, consider the calories you'll burn in a shorter duration. If you weigh 150 pounds, a plank will help you burn between three and four calories per minute.
